The building's interior is also expected to achieve a 6 Star Green Star rating.

Melbourne Water’s new headquarters has achieved a 5 Star NABERS rating (NABERS is Australia’s green building rating system). And it is expected to receive a 6 Star NABERS rating following a period of occupancy. The building’s interior is also expected to achieve a 6 Star Green Star rating.

To minimize water usage, the builders installed 84 Norwegian JETS vacuum drainage toilets throughout the building. The innovative toilets are expected to cut water usage from 4 liters per flush to just 0.8 liters. The building also features a rainwater harvesting and catchment system. After rainwater is filtered it is used in toilets throughout the building.

Construction on the building began in 2010 and finished earlier this year. The modern new building is expected to serve as a gateway to Docklands and the Digital Harbour neighborhood in Melbourne. “The urban design objectives included activating this landmark site in Docklands and creating an energised public realm for the community,” said Woods Bagot Associate Hazel Porter in a statement. “We have developed an iconic and recognisable built form that integrates with the existing Docklands urban fabric and provides a best practice environmental response.”
